<em>The answer is: your GPS unit cannot send signals to the satellite when it cannot reach it by line of sight.

</em>
<em>GPS signals are based on frequencies that can be blocked by solid objects (like walls and roofs). A GPS device is using a series of satellites to detect and see where it is physically located. These frequencies are sent from these plates (satellites) and we cannot expect it to go through all kinds of barriers. When you use a GPS inside a building, a wide variety of physical barriers and potential interference sources make it difficult for the device to detect your location accurately.

Explanation:
Two dimensional array contain both rows and columns. Each row represented one record and each column represent one filed in that record.
for ex: int grades[5][3];
here array grades contains 5 rows and in each row we have 3 columns
if we have grades[i][j] then " i " represents number of rows and j represents the number of columns in that row.
j<grades[i].length represents i=0 to 2[here no of columns are 3, array index starts from 0 to 2]
The Answer is D
